Fix DELETE query in derived delete operations

- Use correct ID column for child entities in JdbcDeleteQueryCreator
- Remove getIdDefiningParentPath() to reference current entity ID
- Rename parentIdColumns to idColumns for clarity
- Add test case for custom ID column name (@column("CHILD_ID"))

Fixes errors when deleting child entities with non-standard ID column names.

Fixes #2123
